"When a train of ideas is very familiar to the mind, they often follow one another in the memory without any laborious recollection, and so as to arise almost instantaneously and mechanically; as in writing, singing, &c. the traces between them being worn like beaten roads."
— Doddridge, Philip (1702-1751)
Locke's Ess. I. ii. c. x. § 3.
8. The power of recollecting differs extremely at different times: and 'tis generally strongest, when we are most brisk and lively.
9. We remember that best in the morning, which we learnt just before we went to sleep: because, say the Cartesians, the traces made then are not apt to be effaced by the motions of the spirits, as they would, if new objects of sensation had presented themselves; and during this interval, they have (as it were) time to stiffen.
10. Sensible ideas gradually decay in the memory if they be not refreshed by new sensations; the traces perhaps wearing out: yet they may last many years.
Locke's Ess. I. ii. c. x. § 4, 5.
11. When a train of ideas is very familiar to the mind, they often follow one another in the memory without any laborious recollection, and so as to arise almost instantaneously and mechanically; as in writing, singing, &c. the traces between them being worn like beaten roads.
Locke's Ess. I. ii. c. xxxiii. § 6.
12. The memory is a faculty which is almost incessantly exercised while thought continues; (though the instances of laborious recollection are comparatively few:) nor do we ever find the human mind entirely stript of it, though it be often impaired.
